A continuous humidity and solar-light dual responsive intelligent solid Mg-moisture battery (SMB) with a graphdiyne nanosheets array was fabricated. The integrated works based on new concept of chemical bond conversion the surface that is grown in situ 3D melamine sponge (GDY/MS). unique structure, excellent catalytic, semiconductor performance GDY endows GDY/MS some outstanding characteristics trapping transferring water molecules, catalyzing HER, utilizing solar energy, making generation cathode for high-performance SMB. GDY/MS-based smart SMB (GSMB) can be continuously tuned by solar-light. GSMB shows significant positive correlation between open circuit potential (OCP) humidity, while natural band gap makes it further act as photoelectrode to capture light generate photoelectrons. applied self-power monitor an ultrafast response time <0.24 s, recovery <0.16 sensitive (36,600%) respiratory sensing performance. This simple efficient battery-made strategy represents future development direction supply equipment, electronic devices, integration.
